O2 Telefonica Germany and Nokia have aggregated sub-6 GHz spectrum frequencies in an industry-first two-component provider uplink Service Aggregation (CA) trial on a 5G Standalone Community. Nokia has already demonstrated 4 element provider downlink 5G Service Aggregation and uplink Service Aggregation on the millimeter wave spectrum. Nokia is the primary to mix sub-6 GHz spectrum with O2 Telefonica Germany to extend uplink throughput.
Service Aggregation
Service Aggregation allows operators to maximise their spectrum belongings to realize higher throughputs and enhance subscribers’ 5G expertise. As well as, by enabling enhanced UL community usability on the cell edge with stronger dependability and decrease latency, provider aggregation will improve 5G efficiency.

Cell operators will have the ability to allow new industrial use circumstances for verticals such because the automotive {industry} and dwell broadcasts of occasions and digital actuality experiences for customers and enterprises, paving the best way for the metaverse.
Location of Trial
A trial that utilized O2 Telefonica’s dwell business community was held on the firm’s innovation cluster near Berlin. Nokia offered options from its AirScale portfolio, together with Baseband, huge MIMO, and RRH merchandise powered by its Reefshark chipset.
Part Service Specification
MediaTek offered its 5G cellular platform utilizing the MediaTek Launch-16 M80 modem built-in into the MediaTek Dimensity 9000 flagship chipset. The businesses used the mixture of a 20 MHz provider on the 1800 MHz band (n3) and a 70 MHz provider on the three.6 GHz band (n78) utilizing Service Aggregation know-how to realize a peak throughput of 144 Mbps.
Dr. Ho-Chi Hwang, Normal Supervisor of Wi-fi Communication System and Partnerships at MediaTek, stated: “The mixture of spectrum frequencies using Service Aggregation delivers premium protection and capability to cellular subscribers the place it’s wanted. Our new 5G cellular platforms using the M80 modem are basic to delivering this achievement and we look ahead to persevering with to assist our {industry} companions to push new boundaries within the improvement of 5G.”
Mallik Rao, Chief Know-how & Data Officer at O2 Telefonica, stated: “With frequency bundling, we’ll allow our prospects to take pleasure in quicker downloads and uploads in our 5G community sooner or later.”
“Service Aggregation software program enhances our high-performance AirScale portfolio, putting Nokia on the forefront of offering applied sciences that assist cellular operators in maximizing radio community efficiencies,” stated Mark Atkinson, SVP of Radio Entry Networks at Nokia.
